RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
